A new genus of the family dictyopharidae (Homoptera) from Argentina

A new monotypical genus with a new species, Phormotegus lenociniosus gen. et sp. n., is described from Argentina. The new genus is closely related to the genera Taosa Distant and Brachytaosa Muir, but differs from them in the reticulate venation of the submacropterous fore wings with outcurved apices and in the unique position of the hind wings projecting laterally from the apices of the fore wings.     

A new species of the shore-fly genus <Emphasis Type="Italic">Notiphila</Emphasis> (Diptera,Ephydridae) from Thailand

A new shore-fly species, Notiphila thaica sp. n. from Thailand, is described. The species is characterized by the following features: antennae yellow, eye-to-gena index equal to 7: 1, all tibiae and tarsi yellow, and setae on abdominal segments III and IV long and pointing posteriorly. The species is similar to Notiphila puncta de Meijere in the presence of numerous brown stripes on the thorax, but differs in the absence of velvety-black spots on the frons, the presence of two strong facial setae, and in the one-color wings. The new species is also very similar to N. phaea Hendel in the structure of the genitalia, but differs in the striped coloration, larger body, and apically widened surstyli. A key to the Oriental species of Notiphila is given.

A new species of the genus <Emphasis Type="Italic">Coccophagus</Emphasis> Westwood (Hymenoptera,Chalcidoidea, Aphelinidae) inhabiting ants’ nests (Hymenoptera,Formicidae) in Malaysia

Coccophagus brachypterus sp. n. is described from Malaysia. The new species differs from the closely related C. silvestrii Compere in the black hind femur and blackish largest part of hind tibia. The new species is also characterized by shortened fore wings with the apices not reaching the abdominal apex.     

World Catalogue of the Family Ratardidae (Lepidoptera,Cossoidea) with Description of a New Species from Thailand and Establishment of New Synonymy and a New Status for <Emphasis Type="Italic">Ratarda javanica</Emphasis> Roepke, 1937

An illustrated catalogue is given of the family Ratardidae in the world fauna which includes 10 species from 3 genera. A new species, Callosiope elenae Yakovlev sp. n., is described from Lampang Province, Thailand. Externally, the new species differs well from the type species of the genus, C. banghaasi. The fore wing of C. elenae sp. n. has a pattern of alternating wide black bands against pure white background (in C. banghaasi, the fore wing is strongly darkened, without bands). The hind wing of C. elenae sp. n. shows a pattern of large dropshaped black smears at the wing edge and a more or less expressed spotted pattern in the discal and postdiscal areas (in C. banghaasi, the hind wing is completely black, with no pattern). A new synonymy: Ratarda marmorata Moore, 1879 = Ratarda guttifera Hering, 1925 syn. n. and a new status: Ratarda mora javanica Roepke, 1937 stat. n., are established. Ratarda excellens (Strand, 1917) is recorded in the fauna of Thailand for the first time.     

Wing morphology of a new Cretaceous praying mantis solves the phylogenetic jigsaw of early‐diverging extant lineages

The extremely derived morphology and behaviour of extant praying mantises combined with a scarce record of fossil relatives introduce significant challenges to tracing their evolution from Palaeozoic stem‐dictyopterans. Extant members of Chaeteessidae, Mantoididae and Metallyticidae could be invaluable to resolving the mantodean tree, yet their inclusion in phylogenetic analyses led to conflicting hypotheses due to their highly disparate respective morphologies. In this contribution, we present Labradormantis guilbaulti gen. et sp.n. , a new fossil species described from both fore‐ and hind‐wing imprints discovered in the Redmond Mine locality (Late Cretaceous, Cenomanian, Redmond Formation; Labrador, Canada). The examination of its hind‐wing AA2* supports the hypothesis that this structure, unique to Chaeteessidae among extant mantises, is a true vein and that its occurrence represents a plesiomorphy for Mantodea. A parsimony analysis including newly coded wing‐related characters further established that L. guilbaulti gen. et sp.n. displays a unique combination of plesiomorphic and apomorphic character states that situates it within the extinct family Baissomantidae. This dataset resolved the phylogenetic relationships of early‐diverging extant lineages as (Chaeteessidae (Mantoididae (Metallyticidae, Artimantodea))), and suggested that the Eocene Lithophotina floccosa Cockerell might be a close relative of extant metallyticids. It also indicated a trend towards increased modularity within mantis fore‐wings, in contrast with a trend towards increased morphological integration in their hind‐wings, both of which are potentially associated with improved flight performance for modern mantises. This study emphasizes the importance of fossils for resolving phylogenetic relationships and for introducing transitional phenotypes to infer ancient evolutionary trends of extant derived clades.     

Two new species of the genus Chablisea Gauld et Dubois (Hymenoptera: Ichneumonidae: Pimplinae) from Vietnam

Two new species of the genus Chablisea Gauld et Dubois, 2006 are described from Vietnam based on ichneumonid material collected from 2002 to 2008. Chablisea condimenta sp. n. differs from other species of the genus by the absence of the second abscissa of hind wing vein Cu1, narrower hind femur (5.2 times as long as wide), and yellow subapical, lateral spots on metasomal tergites 2–5. Chablisea khuatdanglongi sp. n. is characterized by its face as high as wide, yellow with a median black stripe extending to a black transverse band at the base of the clypeus. One species, C. albifacialis (Kusigemati, 1984) is a new combination.

New and little known species of the family Saldidae (heteroptera) from india and adjacent countries

Data on 13 species of the family Saldidae distributed in India, Pakistan, Afghanistan, Nepal, and Vietnam are reported. Two new species, Macrosaldula indica sp. n. (Himachal Pradesh) and Saldula pericarti sp. n. (Jammu and Kashmir, Himachal Pradesh), are described from the Himalayas. Macrosaldula indica is similar to the dark specimens of M. scotica (Curtis, 1835) and M. variabilis variabilis (Herrich-Schaeffer, 1835) of the scotica group, but differs in a shorter body and in the structure of the genitalia. The montane Middle Asian M. tadzhika (Kiritshenko, 1912) is larger and differs from the new species in the color pattern of its fore wing and in a short and arched paramere. An isolated dark spot on the fore tibia and a pale pattern on the corium identify Saldula pericarti sp. n. as a member of the saltatoria group, but the species differs from the other members of this group in the presence of erect hairs on the head, antennae, pronotum, and wings (the character of the orthochila group). New records of Micracanthia minor Hamid et Sultana, 1972, comb. n., are made in Western and Eastern Pakistan. Micracanthia ornatula (Reuter, 1882) is found for the first time in Nepal and Vietnam, Saldula burmanica Lindskog, 1975 and S. palustris (Douglas, 1874), in Pakistan, and S. pilosella (Thomson, 1871), in Afghanistan.     

A new species of the genus Falconius Bolívar, 1898 (Orthoptera: Tetrigidae,Scelimeninae) from Vietnam

Falconius tschernovi sp. n. is described from Vietnam. The new species is closely related to F. dubius Günther, 1938 from Malaysia (Borneo) and F. guangxiensis Zheng et Jiang, 1997 from China (Guangxi Zhuang Autonomous Region), but differs from both in the presence of two pairs of additional lateral keels on the disc of the pronotum, in the armament of the fore femur, in the narrow hind femur, and in the coloration of the hind tibia.

A new species of the genus <Emphasis Type="Italic">Trixagus</Emphasis> Kugelann, 1794 (Coleoptera,Throscidae) from Iran

Trixagus baluchicus sp. n. from southeastern Iran is described. The new species is similar to T. duvalii (Bonvouloir, 1859), but differs from the latter in the narrower body more strongly tapered posteriorly, pale rustybrown coloration, less transverse pronotum, sparser punctation, distinct punctures on the elytral interstriae, somewhat narrower antennal club, wider parameres evenly convex at sides, and more elongate phallobase enlarged only in the basal third.     

Fine nanostructural variation in the wing pattern of a moth <Emphasis Type="Italic">Chiasmia eleonora</Emphasis> Cramer (1780)

Butterflies and moths possess diverse patterns on their wings. Butterflies employ miscellaneous colour in the wings whereas moths use a combination of dull colours like white, grey, brown and black for the patterning of their wings. The exception is some of the toxic diurnal moths which possess bright wing colouration. Moths possess an obscure pattern in the dorsal part of the wings which may be a line, zigzag or swirl. Such patterns help in camouflage during resting period. Thus, the dorsal wing pattern of the moth is used for both intra- as well as inter-specific signal communication. Chiasmia eleonora is a nocturnal moth of greyish black colouration. The dorsal hindwing possesses yellow and black colour patches. A white-coloured oblique line crosses both left and right fore- and hindwings to form a V-shaped pattern across the dorsal wing. This V-shaped pattern possesses a UV signal. Closer to the body, the colour appears darker, which fades towards the margin. The fine nanostructural variation is observed throughout the wings. This study elucidates the wing pattern of the geometrid moth C. eleonora using high-resolution microscopy techniques that has not been described in previous studies.     

One new and one little known species of Chrysidid wasps of the genus <Emphasis Type="Italic">Chrysis</Emphasis> (Hymenoptera,Chrysididae) from the northern Caucasus

A new species, Chrysis vicana sp. n., and the previously unknown male of Ch. neobule are described. The basic morphological differences between the new species and the closely related Chrysis neobule Sem. are given. Chrysis vicana differs from Ch. neobule in the presence of an intense blue sheen on the tegulae and the 1st antennal segment, in the clearly pronounced and short frontal carina, in the coloration of abdominal sternite II, in the brown tarsi, almost black venation, and closed radial vein of the wings. Chrysis vicana is recorded on clay and sandy slopes, and Ch. neobule, on clay and sandy slopes and in dead woods in the middle part of the Kuma River basin (Stavropol Territory).     

Seasonal variability of wing length and eyespots in populations of <Emphasis Type="Italic">Erebia ligea</Emphasis> (L.) (Lepidoptera,Satyridae) in the Middle Urals

The flight period of Erebia ligea (Linnaeus, 1758) in the Sysert District of Sverdlovsk Province lasts from early July until early August only in the odd-numbered years. The species is characterized by protandry, its males emerging 5–7 days before females. Erebia ligea manifests sexual and seasonal variation of the wing length and diameter of the eyespots in the Middle Urals. According to the literature and newly obtained data, the relative male/female wing length varies within the species range. The vectors of the seasonal variation of the body size are opposite in the males and females: in early summer the largest males and the smallest females occur, then mediumsized individuals appear, while the smallest males and the largest females fly at the end of the warm period. Although the males of Erebia ligea are larger than females, the latter have larger eyespots on the wings. Seasonal variation of the diameters of the forewing eyespots is largely similar in the two sexes: individuals with larger spots appear earlier in the season than those with small spots. The eyespots treated as phenes in this study develop on the wings only if the remaining spots of the wing pattern attain a threshold size. A threshold nature was shown for P4 spot in M ₃-Cu ₁ cell of the fore wing and G2 spot in cell M ₁–M ₂ of the hind wing. Individuals with and without phene G2 have opposite vectors of seasonal variation of the sizes of the rest spots of the hind wing pattern. It is apparently the threshold character of variation of these elements of the wing pattern that defines the variation of the proportion of phenetic combinations of the eyespots in the individuals emerging in different periods of the season. Describing phenetic variation at the population level, one should remember that the percentage of the “morphs” or phenetic combinations may vary during a season, especially in the protandric species.     

Fungal Infection of Mantis Shrimp (<Emphasis Type="Italic">Oratosquilla oratoria</Emphasis>) Caused by Two Anamorphic Fungi Found in Japan

Two fungal pathogens of the mantis shrimp (Oratosquilla oratoria) in Yamaguchi and Aichi Prefectures, Japan are described as the new species Plectosporium oratosquillae and Acremonium sp. (a member of the Emericellopsis marine clade). Both fungi infect the gills of the mantis shrimp, which become brown or black due to melanization. The former species is characterized by its slow growth on artificial seawater yeast extract peptone glucose (PYGS) agar, pale yellow to pale orange or grayish yellow colonies, short cylindrical solitary phialides with a wavy tip, and one-celled ellipsoidal conidia. Although lacking the two-celled conidia demonstrated by the type species Plectosporium tabacinum, the taxonomic placement of the new species was confirmed by DNA sequence analysis of the internal transcribed spacer (ITS) region of ribosomal DNA (ITS1, 5.8S rDNA and ITS2). Acremonium sp., the other causal pathogen, differs from P. oratosquillae by its fast growth on PYGS agar, pale orange to salmon-colored colonies, long, slender conidiophores consisting of solitary phialides with tips lacking an undulate outline, and typically cylindrical conidia. Analysis of ITS and β-tubulin gene sequences placed this fungus within the phylogenetically distinct Emericellopsis (anam. Acremonium) marine clade. Various physiological characteristics of both pathogens were also investigated. This is the first report of a fungal infection found on the mantis shrimp in Japan.     

New species of the weevil genus <Emphasis Type="Italic">Pseudorchestes</Emphasis> (Coleoptera,Curculionidae) from the central Palaearctic region

Three new species of the genus Pseudorchestes Bedel are described. Pseudorchestes olgae sp. n. known only from the Dzhanybek Research Station is similar to Ps. abdurakhmanovi Korotyaev, 1993 from Daghestan and Southwestern Kazakhstan but differs in the narrower frons, sparse white scales on the frons and on the underside of the head, longer and narrower antennal club, less strongly curved hind tibia, and larger size. Pseudorchestes tschernovi sp. n. from the Lower Volga River basin, Kazakhstan, and Kyrgyzstan differs from all the known congeners, except for Ps. convexus sp. n. from the Trans-Altai Gobi (Mongolia), in the strongly reduced wings which are only half as long as the elytra, and from the latter species, in the longer rostrum, paler antennae and legs, wide and apically excised scales on the elytra, and in the antennal club short and ovate in both sexes and lacking dense velvety pubescence in the male.     

Doratomantispa burmanica n. gen., n. sp. (Neuroptera: Mantispidae), a new genus of mantidflies in Burmese amber

A new genus and new species of mantidflies, Doratomantispa burmanica n. gen., n. sp. (Neuroptera: Mantispidae), is described from Burmese amber. Diagnostic characters of the new genus are small body size, trichosors present around entire wing margin except basally, protarsus 5-segmented with paired, simple claws but no aroleum, profemur bearing six cuticular spines, inner surface of protibia with row of peg-like protrusions, Sc meets R₁ in region of pterostigma, costal space greatly narrows toward wing apex, with 16 veinlets in costal space on front wing while costal veinlets on hind wing are replaced by trichosors and CuP absent in hind wing. The abdomen of the mantidfly is filled with large spheres resulting from a possible rickettsial infection. Phoretic heterostigmatid mites are adjacent to the wings of the fossil.     

<Emphasis Type="Italic">Leptopus marusiki</Emphasis> Vinokurov,a new species of the bug family Leptopodidae (Heteroptera) from Northern India

A new species, Leptopus marusiki Vinokurov, sp. n., of the family Leptopodidae is described from northern India (Himachal Pradesh State). The new species is closely related to the Western Palaearctic L. hispanus Rambur, 1840, which is distinguished by a dark transverse spot on the apical part of the corium and the pale colored femora. The known Indian Leptopus species are distributed in the south and characterized by the following features: L. decus Drake, 1955 has the brown body and long 1st antennal segment; the lower part of the head of L. scutulus Drake, 1954 bears 4 very long spines, the fore femur bears 2 rows of very long spines (5 in each row). L. travancorensis Distant, 1910 differs in the paler coloration; the 1st and 2nd antennal segments, collar and posterior margin of the pronotum, and legs are ochreous.
